Metals have a high density and they feel heavy so as magnesium is a metal it will not float in water due to the tight compression on the molecules packed in it.
no
No, magnesium won't float in water. It's almost twice as dense. Oh, and magnesium will react with water, but only slowly. Use the link below for more facts. But it will float when reacting with some acid.
NO
no, magnesium never floats in acids...........
No, unless shaped as a boat, and no.
Magnesium oxide will react with water to form Magnesium Hydroxide. Magnesium Hydroxide will not reat further with water
No. Magnesium oxide is not soluble in water. On contact with water it will form magnesium hydroxide.
What sediment float in the water
Jeremejevite does not float on water.
I have a marker which float in water.
Yes it does float in salt water.
Magnesium oxide react with water and magnesium hydroxide is formed.
